What Monsters fit the "realist" tone

Well, except for Gabara and Minilla

Well, when I said Zilla was pretty realistic, I thought the size and rather weakness. I totally forgot about Oodako.

@Gman: Lol!

On the subject, the most "realistic" kaiju in the Godzilla universe would possibly be any of the mechs (except MKG), or perhaps any of the insect kaiju. 

re·al·ist [ree-uh-list] 1. a person who tends to view or represent things as they really are. 2. an artist or a writer whose work is characterized by realism. 3. Philosophy . an adherent of realism. adjective 4. of or pertaining to realism or to a person who embodies its principles or practices: the realist approach to social ills; realist painting. 

HFTT, you need to use the word realistic, that is the correct word for this topic. If any kaiju are realistic, it's the giant octopus, not Zilla.

Well its almost unianimus Ooodako(the gaiant octopus) is the most realistic toho monster

So, I'm gonna throw this debate on its head right now..........

Realistic monsters are.......... mostly not great. Realistic aspects applied to monsters? It can work if done right. As I've brought up countless times in the past regarding the idea of realistic monsters, the very concept is unrealistic in and of itself. But, as modern movies can attest to, if you add certain aspects of realism into the unrealistic concept, such as how the world around it is defined by its presence, some general features about it, etc., it can work wonders to alleviate the general problems of suspension of disbelief.
